Top 10 Backlink Checker Tools for SEO in 2026
A backlink checker is a tool that crawls the web to show which sites link to a domain, along with the authority, anchor text, and follow status of each link. The right choice depends on whether you need deep competitor research, ongoing monitoring through a dedicated backlink monitoring tool, or just a free way to see who links to your own site, since no single tool wins at all three.
What Is a Backlink Checker
This means crawling its own index of the web and reporting which pages link to a given domain, showing metrics like referring domains, anchor text, and a proprietary authority score for context. Backlinks remain one of Google’s strongest ranking factors in 2026, and a growing share of AI Overview citations pull from pages that already rank well, which links still help achieve.
Every checker relies on its own crawler and its own partial index, not Google’s actual database, so no tool’s backlink profile is complete. Cross-referencing two tools before making a real decision, like disavowing a link or greenlighting a guest post placement, is standard senior practice, not overkill.
How We Evaluated These Backlink Checker Tools
Each tool below was assessed on backlink database size and refresh speed, the depth of its authority and quality metrics, whether it is built for discovery, monitoring, or both, and current 2026 pricing. Free tools were judged on how much real data they hand over before hitting a paywall.
| Tool | Starting Price (2026) | Best For | Signature Metric |
| Ahrefs | ~$29-$129/mo | Deepest backlink data | Domain Rating (DR) |
| Semrush | ~$140/mo | All-in-one marketing platform | Authority Score |
| Moz Link Explorer | ~$99/mo | Simple, well-known metrics | Domain Authority (DA) |
| Majestic | ~$50/mo | Link quality forensics | Trust Flow / Citation Flow |
| SE Ranking | ~$45-$65/mo | Budget-friendly all-in-one | Domain Trust |
| Linkody | ~$15/mo | Ongoing link monitoring | New/lost link alerts |
| Ubersuggest | Free, then ~$29/mo | Beginners on a budget | Domain Score |
| SEO SpyGlass | Free, then ~$129/yr | Desktop penalty-risk analysis | Penalty Risk |
| Serpstat | ~$50-$69/mo | Visual reporting, all-in-one | Serpstat Domain Rank (SDR) |
| Google Search Console | Free | Your own verified site only | N/A (raw link data) |
Top 10 Backlink Checker Tools
1. Ahrefs
Ahrefs runs one of the largest backlink indexes in the industry, reported north of 35 trillion known links, and it remains the practitioner default for competitor research and link prospecting. Its Domain Rating metric is the most widely cited authority score in outreach pitches, and its backlink data is generally considered to refresh faster than most competitors.
Pricing runs roughly $29/month for the limited Starter tier up to $129/month for Lite and $249/month for Standard, and Ahrefs no longer offers a free trial beyond its free Webmaster Tools, which only covers domains you own and verify. The honest trade-off: Ahrefs is priced for professionals, and the jump from Starter to a genuinely useful tier is steep.
2. Semrush
Semrush bundles backlink analysis into a much broader marketing suite covering PPC, content, and social alongside SEO. Its dedicated Backlink Audit tool flags toxic links and suggests disavow candidates, and its backlink index is comparable in scale to Ahrefs’.
Entry pricing sits around $140/month for the Pro plan, climbing to roughly $250/month for Guru and $500/month for Business. The trade-off: you are paying for a full marketing platform, which is a poor fit if backlink data is genuinely all you need.
3. Moz Link Explorer
Moz popularized Domain Authority and Page Authority, and those two metrics remain the most recognized shorthand in the industry for site strength, even among people who have never opened Moz itself. Link Explorer also includes Spam Score, a 0-17 point scale estimating how likely a linking domain is to be spammy.
Moz Pro starts around $99/month and includes a 30-day free trial, longer than most competitors offer. The trade-off: Moz’s backlink index is smaller than Ahrefs’ or Majestic’s, so competitive link gap research tends to surface fewer results here.
4. Majestic
Majestic is a pure backlink specialist with no keyword research or content tools, and it built its authority model differently than everyone else on this list. Trust Flow measures how close a site sits to a manually vetted set of trusted seed sites, while Citation Flow measures raw link volume regardless of quality, and the ratio between the two is often more revealing than either score alone.
Plans start around $50/month for Lite and $100/month for Pro, with no free trial, though a limited free tier exists for sites you verify. The trade-off: the interface feels dated next to Ahrefs (see our full Majestic vs Ahrefs comparison), and you will need a separate tool for keyword or content work.
5. SE Ranking
SE Ranking bundles backlink monitoring into a full SEO toolkit at a noticeably lower price than Ahrefs or Semrush, with white-label reports available even on mid-tier plans. Worth flagging: SE Ranking restructured its pricing in late 2025, retiring the old Essential/Pro/Business names, so treat any specific number you see quoted elsewhere as likely outdated.
As of 2026, entry pricing runs roughly $45 to $65 a month depending on billing terms and when you check, climbing past $100/month for higher tiers. The trade-off: its backlink index is smaller than the specialist tools, so it works better as a generalist’s secondary check than a primary research tool for aggressive link prospecting.
6. Linkody
Linkody is not a discovery tool. It is built to watch backlinks you already have and alert you when one goes dead, switches to nofollow, or gets removed, importing directly from Google Search Console if you want. Its built-in disavow file generator flags toxic links and prepares a ready-to-upload file.
Pricing starts around $15/month for a Webmaster plan covering a couple of domains, scaling up to roughly $150/month for agency-level tracking. The trade-off: Linkody will not help you find new link opportunities or research a competitor, which is a common reason first-time buyers pick the wrong tool here.
7. Ubersuggest
Ubersuggest, from Neil Patel, is the most accessible entry point on this list, with a genuine free tier offering a handful of daily lookups before you hit a wall. Paid plans run roughly $29 to $99 a month depending on tier, occasionally with lifetime pricing options available.
The interface is friendlier for newcomers than Ahrefs or Semrush (see our Ubersuggest vs Ahrefs comparison for the full breakdown), which matters for solo bloggers and small business owners doing their first backlink audit. The trade-off: the backlink index is noticeably smaller than the specialist tools, so serious competitive research will outgrow it quickly.
8. SEO SpyGlass
SEO SpyGlass, part of the SEO PowerSuite bundle, is desktop software rather than a cloud dashboard, which is a real workflow difference from every other tool on this list (see our SEO PowerSuite vs Semrush comparison for how the bundle stacks up against a cloud suite). It includes a distinct Penalty Risk score flagging links that could expose a site to a Google penalty, plus a genuinely usable free version covering up to roughly 1,100 backlinks and a two-competitor comparison.
Paid licenses run from around $129 a year for Professional up to several hundred for Enterprise-level bundles with white-label reporting, priced as a license rather than a monthly subscription. The trade-off: it runs locally on your machine, which means no access from another device without reinstalling, and no live cloud dashboard to share with a team.
9. Serpstat
Serpstat bundles backlink analysis into an all-in-one toolkit with its own Domain Rank metric and notably strong data visualization, including new-versus-lost backlink charts that present well to non-technical stakeholders. Its backlink index, at roughly 1.1 trillion links, is smaller than the top three specialist tools.
Entry pricing runs around $50 to $69 a month depending on plan and billing cycle. The trade-off: if raw backlink database depth is the priority, Serpstat trails Ahrefs, Semrush, and Majestic, but few tools on this list present client-facing reports as cleanly.
10. Google Search Console
Google Search Console is completely free and pulls its Links report straight from Google’s own data, making it the most authoritative source available for one specific job: showing which pages link to a site you already own and have verified. It also includes Google’s own disavow tool for links you want Google to ignore.
The limitation that trips up more people than anything else on this list: Search Console cannot show you a competitor’s backlinks, full stop. It only works for domains you control and have verified, which makes it a mandatory companion to a paid tool rather than a replacement for one.
How to Choose the Right Backlink Checker for Your Needs
Pick based on the job, not the biggest brand name. A free tool like Google Search Console or Ubersuggest covers basic checks on your own site; a paid option like Ahrefs, Semrush, or Majestic is necessary once competitor research or link prospecting becomes a real part of your workflow.
| Metric | What It Actually Measures | Provider |
| Domain Authority (DA) | Machine-learning prediction of ranking probability | Moz |
| Domain Rating (DR) | Ahrefs’ proprietary link-strength score | Ahrefs |
| Trust Flow | Link-graph trust propagation from vetted seed sites | Majestic |
| Authority Score | Composite of link and traffic signals | Semrush |
These four scores are not interchangeable, and a domain can score well on one while scoring poorly on another. A high DA built from referring domains that correlate loosely with rankings is not the same thing as a high Trust Flow built from proximity to genuinely trusted sites, which is exactly why senior link builders check more than one authority score before trusting a prospect list.
Also decide upfront whether you need discovery or monitoring, since these are different jobs. Linkody and Search Console watch links you already have; Ahrefs, Semrush, Majestic, and Serpstat are built to find new ones and research competitors, and most serious campaigns eventually need both categories represented in the toolkit.
Final Thoughts
No backlink checker on this list is wrong, they are built for different jobs. Ahrefs and Semrush earn their price for teams doing serious competitor research, Majestic and Moz answer different questions about authority worth understanding rather than treating as interchangeable, and Linkody or Search Console cover monitoring without any real cost. Pick the tool that matches the actual job in front of you this month, not the one with the biggest name, and revisit that choice as your needs change.
FAQs
Google Search Console is the most reliable free option for your own verified site, since the data comes directly from Google. Ubersuggest offers the most useful free tier for checking other domains, though its index is smaller than the paid specialist tools.
Most free tools cap how many competitor lookups you get before requiring payment, and Google Search Console cannot show competitor data at all since it only covers domains you own and verify. Ubersuggest and Ahrefs’ limited free tools allow a small number of competitor checks before hitting a paywall.
Ahrefs is generally considered stronger specifically for backlink data depth and refresh speed. Semrush wins if you need PPC, content, and social tools bundled with your backlink analysis rather than a dedicated backlink specialist.
Domain Authority is Moz’s machine-learning prediction of how well a site is likely to rank. Trust Flow is Majestic’s measure of how close a site sits to a manually vetted set of trusted sites. They measure different things and often disagree on the same domain.
Paid tools generally run $15 a month for a monitoring-only tool like Linkody up to $250 or more a month for full platforms like Semrush Guru. Free options exist through Google Search Console and limited tiers of Ubersuggest and Ahrefs.
Ahrefs and Semrush both report backlink indexes in the tens of trillions of links, the largest among the tools covered here. A bigger index does not automatically mean better results for every use case, since refresh speed and dead-link verification matter just as much for time-sensitive campaigns.
Yes, it remains the most widely recognized authority shorthand in the industry, even though it is not a Google ranking factor itself. Treat it as one data point alongside Domain Rating and Trust Flow rather than a definitive score on its own.
